RAILWAY-RAIL.

To all whom it may concern:

Be it known that we, JOHN LUNDIE and WILLIAM R. DUNHAM, Jr. bothcitizens of respectively, at I the United States, residing, New' York,New York, and New Haven, Connecticut, have invented certain new anduseful Improvements in Railway-Rails, of which the following-is aspecification.

This invention relates to; railway rails One either for electric orsteam railroads, of the obj ects of the invention Is to provide meansfor seating railway rails upon the wooden ties, theunder surface of therailbase being provided with means for. seating upon and embedding inthe tiess In the case of rails under light wheel loads, tieplates arenot ordinarilyjemployed, so that under the present invention therailrests directly upon andengages the-wood fibers of the ties. Anotherobjectof the invention is, torprovide an inclined rail with a base soconstructed that theline of stress due to the load on the usual beveledwheel-tread passesaxiallythrough the web, and is at right angles to theseries of inclined seats on the bottom of the base, the rail being thusheld firmly to gage without in any way cutting or injuring the'surfaceof the These being among the objects of the present 1nvent1on the sameconsists of certain features Of'COIlSlZIIlClJlOIl and combinations'ofparts to'bei hereinafter described,

and then claimed with reference to the ac companying drawings showingtwoembodi- ;;,roads, according to the present invention;

and i fFig, 3. is an underside view of therail showing thegends I only,the intermediate portion being broken away. a

Although the invention is here shown as applied to inclined rails, someof the features of the invention may be capable of use in a'verticalrail. c Referring, to Figs. 1 and2, the rail has a base 10, and a web11, the web being 'inspecificationof Letters Patent.

clined away from vertical plane. The-rail 1 in Fig. 2 is for steamroads, and has thecustomary head 12.

When thepresentinvention i applied to inclined rails, the entirestructure is inclined relatively to the horizontal, plane off/the;

general undersurface'of the rail ba'se,-that is to say, its transverseaxis is inclined substantially as indicated by the dottedv line a,

Fig. 1; The vertical is indicated by the dot-;

ted line b.

lows: The undersurface isformed by a se ries of inclinedseats-13,preferably connectedby curved portions 14 .In the preferredconstruction, the seats 13 and the Z connecting portions 14 betweentheseats, ex-; tend longitudinally of the rail, preferably;

parallel with the longitudinal axis, of the.

rail.

said planes being perpendicular to the in: clined axis a of the rail;Said seats 13, ex-;

Said seats 13 also extend in inclined planes, 7 preferably parallel witheach other, i

cept for small seating portionswhich may.

' be at the edges of the base of the'rail, are

both of substantially the same width. In

Fig. 1, the dotted line 0 indicates the direc-- tion of inclination ofthe seating or step surfaces l3-transversely of the rail, while'the.dotted line (Z is a line substantially parallel withthelongitudinal axisof any tie. j The car wheel 15. is of the usual beveled or stand-,-

ard type, having abeveled tread'16.,

It will be seen from the preferred forr'n ofthej invention that theseating surfaces 13 are the majorseatingsurfaces of,the,rail,: andthatthey offer more resistance to the, seating of the rail inthe top ofa woodentie than the connectingsurfaces 14, which,

lie at a greater angle of inclination to-the; plane of the base, or topsurface of the tie,

and which may be said to constitute minor seating surfaces.

From the above descriptionof the pre-,.

ferred form ofthe invention it will be seen that the line of pressure-inthe wheel and the line of stress in the rail are co-incident,.;

being represented by the line a. It' will also be seen that the tread ofithe wheel and the;

bearing surface therefor of the rail are substantially at right anglesto the line a, at any point along the rail over which the wheel ispassing. It will also be seen that if the left-hand end of any tie beconsidered the outside of the track, the shoulders or surfaces at 14will be at those sides of the. successive seating surfaces 18, exceptingthe I.

last one to the right, which are away from that end of the tie. It willalso be seen by the arrow indications in Fig. 1 that the re- 1 sistingforces of a tie are at right angles to the direction of seating, thuspreventing slipping- The action may be described in the followingterms,-so far as the preferred embodiment of the invention is concerned:

The line of stress a, due to the load on the usual beveled wheel tread16 passes axially through the web, and is at right angles to the seriesof inclined seats 13 on the bottom of the base, such seats beingparallel with the bevel of the wheel tread, so that the rail is heldfirmly to gage. It will be seen that the described undersurface of thebase will not, in anyway cut or injure the surface of the tie, as itmerely becomes slightly embedded therein,'due to the preferred shallowor slight depth of the ribs, the fibers I of the tie accommodatingthemselves to the contour of the said under surface.

' In one aspect the under surface of th base of the rail may beconsidered as developed in waves, the crests of which at 14 "and theintermediate troughs of which extend in lines substantially parallelwith the longitudinal axis of the rail; and preferably, the so-formedribs are defined by planes, joined by curves at the juncture of*neighboring ribs and at the edge of each and it is believed unnecessaryto specify just what objections to vertical rails of the type referredto are overcome, when the invention is applied to inclined rails.

' It is obvious that the invention is susceptible of more or lessmodification,as, for instance, it may be applied to vertical rails,-andthat such modifications would still be within the appended claims.
